Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration damping systems for transport equipment, such as vehicles and ships, are inadequate in addressing extreme low-frequency high-amplitude vibrations and fail to provide self-balancing functionality, especially under complex road conditions.
Innovation Solution
A self-balancing vibration damping system that includes an active vibration damping module with two rotating assemblies controlled by a sensor module and a control module, allowing for synchronous operation to achieve two degrees of freedom in rolling and pitching, thereby maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If passive vibration damping measures are adopted (such as vibration damping springs or damping pads), then high-frequency low-amplitude vibration is dampened, but extremely-low-frequency high-amplitude vibration cannot be dampened and self-balancing function is lacking
Solution Approach 1:
The vibration damping system is segmented into multiple independent rotating assemblies (first rotating assembly, second rotating assembly, etc.), each capable of operating in different frequency ranges. This allows the system to handle both high-frequency low-amplitude vibrations and low-frequency high-amplitude vibrations simultaneously through distributed functional modules.
Solution Approach 2:
The patent employs active control mechanisms where rotating assemblies can dynamically adjust their operational parameters based on real-time vibration conditions. The control module receives sensor data and actively modulates the rotating assemblies to provide adaptive damping across varying frequency ranges, transforming the system from static passive damping to dynamic active damping.
2Object-affected harmful factors
If active suspension or anti-roll functions are added to achieve better vibration control, then damping effect is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple vibration damping functions into an integrated system where rotating assemblies serve dual purposes: they provide active damping control while also enabling self-balancing functionality. The control module, sensor module, and rotating assemblies work as a unified system, eliminating the need for separate complex active suspension and anti-roll systems.
Solution Approach 2:
The system incorporates self-balancing capability through the rotating assemblies that automatically adjust to counteract vibrations and maintain equilibrium. The sensor module continuously monitors vibration conditions and the control module autonomously adjusts the rotating assemblies without requiring external intervention, enabling the system to self-regulate and maintain optimal damping performance.
3Stability of the object's composition
If multiple rotating assemblies operate synchronously to achieve two degrees of freedom for self-balancing, then stability and comfort are improved, but device complexity increases
Solution Approach 1:
Each rotating assembly is designed with multi-functionality, capable of operating in different orientations and frequency ranges. The first rotating assembly can be configured for pitch control while the second handles roll control, but both can adapt to various operational requirements. This universal design reduces the need for specialized components for each degree of freedom.
Solution Approach 2:
The patent introduces a vertical dimension to the rotating assemblies, allowing them to be stacked or arranged in multiple layers. This spatial arrangement enables two degrees of freedom (pitch and roll) to be achieved through compact three-dimensional configuration rather than requiring extensive horizontal space, thereby reducing overall system complexity.
